Primary Issue
Most claims are unsupported by the provided FDA label excerpts, including indication and common adverse-effect statements; critical label safety content was not evaluated.
Suggested Improvement
Limit statements to text supported by provided label sections, and include the missing label sections (Indications/Usage, Adverse Reactions with frequency/common side effects, Contraindications/Warnings/Precautions, Dosing/Administration, Drug Interactions) before making or validating such claims.
